This is treated just like a theorem or a postulate in proofs. Corollary to Theorem 4. Angle-Angle-Side Congruence If two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of the second triangle, then the two triangles are congruent. Feedback Privacy Policy Feedback. Reflexive Property of Congruence Reflexive Property of Congruence Because the segment is shared between two triangles, and yet it is the same segment The statement is not true because the vertices are out of order.

Auth with social network: Converse of Base Angles Theorem If two angles of a triangle are congruent, then the sides opposite them are congruent.
